Features t 55% Power Added Efficiency t 35 dBm Output Power t Low Harmonic Distortion t Low Cost, SO-8 Surface Mount Package t 34 dB Gain Applications t GSM Class IV Cellular Handsets t 900 MHz ISM Products t SMR Radio Description The CMM0335 is a highly efficient, 6V power amplifier intended for use in portable cellular handsets and datacom products operating in the SMR, GSM and 902-928 MHz ISM bands. As a pin-compatible member of the new Triniti DXTM amplifier family, the CMM0335 offers maxi- mum performance and flexibility.The CMM0335 is packaged in a low-cost, space efficient SO-8 power package that gives excellent electrical stability and thermal handling performance with a R of less than 18 C/W. The part is designed to require minimal external circuitry for bias matching, simplifying design and keeping board space and cost to a minimum.
